Hamza Sood, an iOS developer, tweeted a series on screenshots of the hidden Activity app found in recently released iOS 8.2 firmware for public consumption. The Activity app, unearth by Sood, is hidden inside the iOS 8.2 and would only appear when the iPhone has been connected to the Apple Watch using the Apple Watch app for iOS.

Developer Hamza Sood has unearthed the hidden Activity app that Apple has put inside its recent iOS 8.2 release. The app will automatically show up on the homescreen once users connect an Apple Watch to their iPhone.

When the Apple Watch is connected to iPhone, Activity app pops up with a splash screen that reads: “The Activity app works with Apple Watch to keep track of your activity and workout history. To start using the app on your iPhone, first set up Activity on your Apple Watch.”

Screenshots clearly shows that the Activity app looks elegant on the iPhone once it’s connected to an Apple Watch. The UI of the app on the iPhone is pretty similar to how the information is shown on the Apple Watch.

The screenshots show that the app displays the total amount of duration the user has stood, walked and exercised throughout the day. Alongside the complete breakdown of user’s physical activity throughout the day, the app also shows the achievements that user has managed to unlock. The Activity app shares you daily activity data, collected through the Apple Watch, with the iOS Health app. It means you Activity data can optionally be made available to the health and fitness apps developed and designed using HealthKit.

So Apple Watch measures all the ways you move, such as walking the dog, taking the stairs, or playing with your kids. It even keeps track of when you stand up, and encourages you to keep moving. Because it all counts. And it all adds up.

Sood noted that the companion Apple Watch app for iPhone has an internal automation mode, but he doesn’t know its purpose. You can see in the screenshot below; a brief mention of something referred to as “the Gizmo.”
